Develop a fundamental understanding of the basic principles of chemical engineering thermodynamics and calculations. 2. Examine and select pertinent data, and solve energy transformations problems. 3. Give examples of important application of thermodynamics laws in chemical engineering and biotechnology processes. List of Open Source Software/learning website: 1. Students can refer to video lectures available on the websites including NPTEL. 2. Students can refer to the CDs which are available with some reference books for the solution of problems using softwares. Students can develop their own programs for the solutions of problems. ACTIVE LEARNING ASSIGNMENTS: Preparation of power-point slides, which include videos, animations, pictures, graphics for better understanding theory and practical work – The faculty will allocate chapters/ parts of chapters to groups of students so that the entire syllabus to be covered. The power-point slides should be put up on the web-site of the College/ Institute, along with the names of the students of the group, the name of the faculty, Department and College on the first slide. The best three works should submit to GTU.
